Abstract

A method and apparatus for preparing a composite, in which the angle between the apparatus base and the apparatus body is adjusted by the elevator device, the solid raw material is loaded into the reactor by the solid feeding device, the main reaction gas, the auxiliary gas and the carrier gas are introduced from the front gas intake unit into the main reaction zone at a preset ratio, followed by the active material deposited on solid particles, the post-processing reaction gas is introduced from the middle gas intake unit to the post-processing reaction zone to form a functional layer on the active material, the prepared composite powder is separated and collected from the gas-solid mixture in the collection device. The exhaust gas is released from the exhaust manifold into an exhaust gas treatment system after minority powder filtered by the filter.

An apparatus for preparing a composite, comprising:

an apparatus base;
an apparatus body;
and
an elevator device disposed on the apparatus base;
wherein the elevator device is configured to adjust an angle between the apparatus base and the apparatus body;
wherein the apparatus body comprises a solid feeding bin, gas intake units, a heating module, a reactor, a collection device, an exhaust unit and a control unit, and the control unit is connected and communicated with the solid feeding bin, the gas intake units, the heating module, the reactor, the collection device and the exhaust unit, respectively;
wherein a solid feeding device is disposed inside the solid feeding bin;
wherein the gas intake units comprise a front gas intake unit and a middle gas intake unit;
wherein a front feeding port is disposed at a first end of the reactor, and a middle feeding port is disposed at the middle of the reactor;
wherein the front feeding port is connected with the solid feeding device and the front gas intake unit, respectively, and the middle feeding port is connected with the middle gas intake unit;
an outlet is disposed at a second end of the reactor, and the outlet is connected with the collection device;
wherein the reactor is divided into a first region and a second region by the middle feeding port, and the first region and the second region are a main reaction zone and a post-processing reaction zone, respectively;
wherein the reactor is wrapped inside the heating module, and the heating module is configured to heat the main reaction zone and the post-processing reaction zone to target reaction temperatures, and maintain the temperatures constant;
wherein the collection device is configured to separate and collect a product from a gas-solid mixture;
and
wherein the exhaust unit is connected with the collection device by an outlet of an exhaust manifold, the exhaust unit comprises a vacuum pump and a filter, the vacuum pump is configured to regulate the internal pressure of the reactor, and the filter is configured to capture powders in the exhaust.
